what are some cases that are elegant looking, example of elengant case is Silencio 650 from CM
I need a case that are:
-Able to accommodate ATX board
-Totally clean look,no window/fan mount on side panel,totally clean as well at front
-Good air flow of course
I would go for the Fractal Design Node 605.
Clean sharp lines, with a stunning front panel. Great for HTPC. And will fit anything you need for gaming or regular computing.http://www.fractal-design.com/?view=product&category=2&prod=95
It is a little pricy, though there are some nice alternatives from Silverstone.
Hope it helps
